  • Feature requested: Maximum number of custom foreign keys per entity
  • Organization ID where you want the feature to be enabled (Click Setup > Company Profile > Company Information):
  • I am the system admin in charge of this feature
  • Organization Edition
  • A strong business case with specific information on what the additional foreign keys will be used for. Increases past the default of 40 will carry potential performance impacts and will need to be reviewed and approved by our Product Management team (NOTE: if this is missing or not strong enough, the request will be denied)
 
5. Our Support Team will review the Case and action as needed.
 
Sandbox
Requests for increasing this limit in sandboxes will be facilitated through a separate case created by support.
If the limit increase has been made on production, the same limit can be applied in sandbox through the use of License Match Tool.
 
Free Editions (Trial Org or Developer Edition)
This increase is not available for Developer Editions. Trial organizations may qualify but you will need to contact your Account Executive or another member of the Account Team instead of logging a case with support.                
 
Note: These requests may take a few days to process because of the approvals needed. Typically, the increase happens in your sandboxes first  followed by your production.
